Homeotropically oriented layers and films of liquid crystals especially on polymeric substrates. The layers and films, which also can be multi-layered films comprising a homeotropically aligned anisotropic film, are preparable by application of an orientation layer to the substrate. The orientation layer can be either an organic surfactant which is fixed in a matrix of a polymeric material or an inorganic thin layer such as aluminum or AlO.

Homeotropically aligned liquid crystal layer and process for the homeotropic alignment of liquid crystals on plastic substrates

Homeotropically oriented layers and films of liquid crystals especially on polymeric substrates. The layers and films, which also can be multi-layered films comprising a homeotropically aligned anisotropic film, are preparable by application of an orientation layer to the substrate. The orientation layer can be either an organic surfactant which is fixed in a matrix of a polymeric material or an inorganic thin layer such as aluminum or Al O .

The invention relates to a process for preparing an optical retardation film comprising at least one layer of an anisotropic polymer material, to a method of rubbing a substrate for the alignment of liquid crystal or mesogenic material that can be used in the above process, to an optical retardation film obtainable by the above process, to the use of such an optical retardation film in a liquid crystal display, and to a liquid crystal display device comprising a liquid crystal cell and such an optical retardation film.
